We use Google Docs on a daily basis and it's an essential part of our working processes. For the most part we're very happy though there are a couple of things worth mentioning that I hope will be improved in the future. Firstly, if you work with multiple Google accounts, it can get frustrating as you switch between Google aps (Gmail, Calendar, Drive, Docs, Sheets, etc) and it seems that the account it assigns for the new tab is often random. This can cause confsion when Docs are not where you thought they were and you cannot save them under a different Google account Drive without making a copy or adding a shortcut which is a bit of a hoo-hah. Secondly, for some unknown reason they did not bother to build in the functionality to select multiple areas of text. This is particularly annoying if you want to edit multiple headings, or change font size of multiple sections, etc. This functionality exists in Word (Shift + select) and it's a bit strange that Google is lagging with such an, in my eyes, essential feature. Let's hope they get up to speed soon.
